<div class="description">
    <p> This sample shows how to configure CKEditor to output valid
        <a class="samples" href="http://www.w3.org/TR/html401/">HTML 4.01</a> code. Traditional HTML elements like
        <code>&lt;b&gt;</code>, <code>&lt;i&gt;</code>, and <code>&lt;font&gt;</code> are used in place of <code>&lt;strong&gt;</code>,
        <code>&lt;em&gt;</code>, and CSS styles. </p>
    <p> To add a CKEditor instance outputting legacy HTML 4.01 code, load the editor using a standard JavaScript call,
        and define CKEditor features to use the HTML compliant elements and attributes. </p>
    <p> A snippet of the configuration code can be seen below; check the source of this page for full definition: </p>
    <pre class="samples">
CKEDITOR.replace( '<em>textarea_id</em>', {
	coreStyles_bold: { element: 'b' },
	coreStyles_italic: { element: 'i' },

	fontSize_style: {
		element: 'font',
		attributes: { 'size': '#(size)' }
	}
